Same situation here.Welcome to the club! We are all 8+ months here with no update. Unfortunately there is very little we can do to move the application along - IRCC works on the application when they feel like, nothing much we can do.
In order to understand what's happening with your application you can order GCMS notes. They take 30 days to arrive and can provide some detail as to what's going on with your application. The quickest thing you can do right now is call IRCC and ask what is the status of your application in terms of: Eligibility, Security and Criminality. Specifically ask for these 3 attributes. You can also ask which Visa Office is processing your application though that isn't necessarily helpful.
At this point you can just try gathering information - apart from that sit tight, wait and hope for the best. Hopefully the wait isn't too long.
AOR: May 9th 2019, I'm an inland candidate.
From the GSMS notes I also came to know that my file is in New Delhi office for processing since Aug-2019.
And there is no update since then.
I've raised 2 webforms specifically to Delhi office (in Dec & Jan) but no reply at all.
My WP and Medical is also about to expire.
Don't know what to do next.
Where are you located
